comment What happens once a brain is full?
This answer only talks about short-term aspects, while the original question is about long-term perspectives, I think.

comment The distance the electromagnetic field of the heart can be detected
I heard such anecdotes from electrical engineering friends. Their circuit was so sensitive that you would see your own heart beat on the oscilloscope just in the vicinity. I don't know what the exact distance was. Perhaps you could as this Q at EE.SE electronics.stackexchange.com ?

comment How does an axon “know” it's not connecting to its own neuron?
@Lennart_96 I'm not a particular expert on neurodevelopment, but it seemed to me that they pretty much grew in many random directions. There were no extracellular matrix or chemicals that would give an overall structural guide to the neurons (though there were glia multiplying simultaneously).

comment How do cats shed their fur?
I would agree if it were only for OP. But what about all the other people who come to Bio.SE to get an answer to this question? For the health of this community, I think having a tiny bit more detail would be a good thing.

@Lennart_96 that study was done with dissociated cortical culture; they formed random connections. (I happened to work with both authors, and did some modeling study myself, but not on the neurodevelopment side.)

It would be extra helpful if you could summarize the content of the links in your response. :)

Can you give us citations on the study you mentioned?

comment Is tactile perception two-dimensional or three-dimensional?
@Anixx en.wikipedia.org/wiki/Vertical_sound_localization combined with other cues, not perfectly, but possible.

comment Is tactile perception two-dimensional or three-dimensional?
@Anixx but you can. Head transfer function and prior knowledge. It's mathematically possible, although not always the case.

comment What is the energy consumption of the brain?
The cortical activity pattern is measurably different between rest and sleep states. I think there would be measurable differences.

One ref for the breakdown of energy costs: Laughlin, S. (2001). Energy as a constraint on the coding and processing of sensory information. Current Opinion in Neurobiology, 11(4):475-480.

Try maximally exhaling, and then hold your breath. ;)
